one guy told me he tows roughly 10-12K(not including weight of truck) very often. They have their own wiring system and are controled from a VSC(variable speed controler) where you can have them come on at a certain temp depending on where you have the temp probe installed in the radiator. The fans didn't change/affect the engine and how it runs at all. Other than the fans, and intercooler, i have a CFM+ large mouth and water injection. Here's a link to the flex-a-lite fans http://www.flex-a-lite.com/auto/html/272-diesel.html. Installation http://www.flex-a-lite.com/auto/278-98278.pdf
